Trophic interaction data and taxonomic information for fish predators and their prey spanning the North East Atlantic and its marginal seas between 1836-2013

Taxonomic information and the diet matrix for fish species-size-classes (rows) and their prey (columns) used to produce feeding guilds via cluster analysis for Thompson et al. (2020) ‘A feeding guild indicator to assess environmental change impacts on marine ecosystem structure and functioning’. Journal of Applied Ecology. The purpose of this study was to propose a food web indicator which has been explicitly called for to inform policy via food web status assessment as part of the European Union’s Marine Strategy Framework Directive and the indicator toolkit supporting The Convention for the Protection of the Marine Environment of the North-East Atlantic (the ‘OSPAR Convention').
